When solving an equation with two variables, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)
Solve 4b + 6b = b - 9z + 7 for b in terms of z.
| -5z + 2\(\frac{1}{3}\) | |
| z + 6 | |
| -2\(\frac{2}{3}\)z + 1\(\frac{1}{6}\) | |
| 1\(\frac{7}{10}\)z + \(\frac{3}{10}\) |
